10. For the cross-linear configuration, there are two components in the decay curve, i.e., a fast decay and a slow decay. The signal in the cross-linear configuration is found to be one order of magnitude smaller than those in the co-circular and co-linear configurations. Such differences are due to two photon coherence between the ground state and the two exciton state (Ref.).
11. The energy of the folded acoustic phonon should decrease with increasing temperature due to thermal expansion. However experimentally obtained ω1 increases. This disagreement will be come from low precision of the fitting.
12. Recently we have observed clear beat structure on the TI FWM signal at 10 K by using a laser pulse that broad spectral width of about 16 meV. The beat structure of the TI FWM signal is due to relatively large phonon sideband signal compared with the experiment in this paper.
